The present invention is generally related to an adjustable button apparatus of a lock applicable for installation in doors of various door thicknesses through a joint length formed by jointing a transmission rod and a driving plate.
BACKGROUND OF THE INVENTIONA conventional lock is applicable for installation in doors of various thicknesses by an adjustable interval between two mounting assemblies and a length-adjustable button apparatus.
Please refer to U.S. Pat. No. 6,929,290 “an adjustable button mechanism of a lock” and
The primary object of an adjustable button apparatus of a lock in the present invention is to adjust a joint length formed by jointing a transmission rod and a driving plate. An adjusting sleeve is movable between a positioning position and an adjusting position for adjusting the joint length formed by jointing the transmission rod and the driving plate so that the lock is applicable for installation in doors of various thicknesses.
An adjustable button apparatus of a lock includes an adjusting sleeve, a transmission rod, a driving plate, a positioning pin and a button, wherein the adjusting sleeve is movable between a positioning position and an adjusting position, the transmission rod is inserted into the adjusting sleeve and comprises an insertion hole, the driving plate is inserted into the insertion hole and comprises a body and a plurality of positioning holes formed at the body, the button is engaged with the driving plate, and the positioning pin is engaged with the transmission rod and being movable in response to the adjusting sleeve. When the adjusting sleeve is located at the positioning position, the positioning pin is inserted into one of the positioning holes of the driving plate to make the driving plate fixedly positioned in the insertion hole of the transmission rod, otherwise, when the adjusting sleeve is located at the adjusting position, the positioning pin separates apart from the positioning hole to make the driving plate movable in the insertion hole of the transmission rod for adjusting the joint length formed by jointing the transmission rod and the driving plate.
The adjustable button apparatus of the lock of the present invention enables to adjust the joint length formed by jointing the transmission rod and the driving plate without using a tool and makes the lock applicable for installation in doors of various door thicknesses. When the adjusting sleeve of the present invention is located at the positioning position, the positioning pin is pressed by the adjusting sleeve to make the positioning pin inserted into the driving plate and to make the driving plate engage with the transmission rod so that the transmission rod and the driving plate act simultaneously. When the joint length longs for adjustment, the adjusting sleeve moves from the positioning position to the adjusting position to make the positioning pin separate apart from the driving plate so that the driving plate is transversely movable in the transmission rod for adjusting the joint length formed by jointing the transmission rod and the driving plate. Thereafter, the adjusting sleeve moves from the adjusting position to the positioning position so as to make the positioning pin pressed by the adjusting sleeve once again and to force the positioning pin to insert into the driving plate for achieving joint length adjustment.

The adjustable button apparatus of the lock 100 of the present invention enables to adjust the joint length formed by jointing the transmission rod 120 and the driving plate 130 without using a tool and makes the lock applicable for installation in doors of various door thicknesses. When the adjusting sleeve 110 of the present invention is located at the positioning position, the positioning pin 140 is pressed by the adjusting sleeve 110 to make the positioning pin 140 inserted into the driving plate 130 and engaged with the transmission rod 120 and the driving plate 130 so that the transmission rod 120 and the driving plate 130 act simultaneously. When the joint length longs for adjustment, the adjusting sleeve 110 moves from the positioning position to the adjusting position to make the positioning pin 140 separate apart from the driving plate 130 so that the driving plate 130 is transversely movable in the transmission rod 120 for adjusting the joint length formed by jointing the transmission rod 120 and the driving plate 130. Thereafter, the adjusting sleeve 110 moves from the adjusting position to the positioning position so as to make the positioning pin 140 pressed by the adjusting sleeve 110 once again and force the positioning pin 140 to insert into the driving plate 130 for achieving joint length adjustment.
While this invention has been particularly illustrated and described in detail with respect to the preferred embodiments thereof, it will be clearly understood by those skilled in the art that it is not limited to the specific features and describes and various modifications and changes in form and details may be made without departing from the spirit and scope of this invention.
